Hi,
Last night after sloooooowly going over a speed bump, all the amber warning lights in my 2016 F-type base came one. Car was running fine before and after. I shut the car off and let it sit for an hour. When I restarted, the check engine light was the only light on. This morning when I started it up, the check engine light is one. I'm hoping this is something my local non-dealer shop can look at but I was wondering what the opinion of my fellow forum folks might have. Loose ground or wiring connection? Just guessing here. Thank you.

 

Yes, the fact that the lights came on after an encounter with a speed bump strongly suggests a loose connection either at the battery or a ground point. The CEL remaining on after the others have gone dark does not necessarily indicate a true mechanical fault. The first thing I would do is to tighten/verify the battery connections and the negative lead connection on the trunk floor.

 

Thank you for responding so fast. I went and checked the connections as you suggested. Nothing seemed loose or otherwise out of whack and when I started the car, the CEL was off (unlike this morning). I took it for a ride over several speed humps and could not recreate the problem. Perhaps what I went over last night was a speed Bump (vs. hump) and whatever slight difference it was caused the connection issue. Whatever it is, can't see taking it into the shop and incurring whatever they might charge to tell me they can't find anything.
